The FIRST step that the systems administrator should perform before altering the configuration of the finance department's database server is B. Change management.
Change management is the process of controlling changes to IT infrastructure, including hardware, software, and documentation. By following a structured change management process, the administrator can ensure that changes are properly evaluated, authorized, tested, implemented, and documented, and that any potential risks or impacts are identified and mitigated.
Before making any changes to the configuration of the finance department's database server, the systems administrator should:
Identify the change: Clearly define what changes need to be made to the server and document the expected results.
Assess the impact: Analyze the potential impact of the change on the server, the application(s) running on the server, and other systems in the enterprise.
Plan the change: Develop a detailed plan for implementing the change, including any necessary backup and recovery procedures, as well as any required testing and validation.
Test the change: Perform testing on the proposed change in a controlled environment to ensure that it will function as intended and not cause any unintended consequences.
Implement the change: After receiving approval, execute the change according to the change plan.
Document the change: After the change has been implemented, document the change and its results, as well as any lessons learned, for future reference.
Capacity planning, backups, and patching are important considerations in maintaining the health and performance of the database server, but they should be secondary concerns after following a structured change management process.
